Abstract

L'invention porte sur un adaptateur optique qui permet de relier directement des connecteurs optiques possédant des surfaces polies différentes en logeant les ferrules aux surfaces polies différentes dans l'adaptateur optique. L'adaptateur optique précité comprend une première et une seconde entretoise et une partie ferrule contenue à l'intérieur de ces dernières. L'adaptateur optique selon l'invention permet de relier facilement les connecteurs optiques sans perte de transmission et sans utiliser de bretelle de continuité électrique. L'invention permet aussi de réduire les coûts de production, étant donné que les bretelles ne sont pas nécessaires.
